EVANSTON (CBS) — One teen is in jail and police are seeking a second after they allegedly rummaged through the pockets of someone they knew at gunpoint, getting away with just two lottery tickets.

Savon Tremain Griffith, 17, of Evanston is charged with one felony count of aggravated robbery, a release from Evanston police said.

The victim told police he was riding his bike in the 2300 block of Emerson on Oct. 25 about 7:45 p.m. when he was approached by two people he knew. They pinned him against a parked car and one threatened him and put a handgun against his side, the release said.

The other offender then went through the victims’ pockets, taking two lottery tickets. Once getting the tickets, the offender punched the victim in the face and both offenders ran away. The victim went home and called police.

Detectives positively identified Griffith as the offender who placed the gun against the victim’s side. Police also were able to identify the other offender, who is still being sought, the release said.

Griffith’s statements to police directly linked him to the robbery, police say.
